FAN.

SPECIFICATION forming part of Letters Patent 0. 730,890, dated June 16, 1903.

Original application filed October 15, 1902, Serial No. 127,381. Divided and this application filed February 21, 1903. Serial No. 144,391. (No model.)

To aZZ whom it may concern.-

Be it known that I, CHARLES A. ECK, a subject of the King of Sweden and Norway, and a resident of Belleville, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in Fans,

of which the following is a specification.

My invention relates generally to fans, and,

has more particularly reference to means whereby a fan will be caused to oscillate or turn from one side to the other as it rotates, and is a companion application to the one filed on the 15th day of October, 1902, Serial No. 127,381.

The object of my invention is to producea structure which is simple, inexpensive, and

efficient and one which will not mar the appearance of the fan.

In carrying out this object my invention I shall describe a fan adapted to oscillate in the manner set forth embodying my invention and afterward point out the novel features in the claims.

In the drawings I have embodied my invention in a suitable form; but changes in construction may of course be made within the scope of the claims.

In the said drawings, Figure l is a front view of a fan embodying my invention. Fig.

2 is a side view of Fig. 1. Fig. 3 shows amodification.

A represents a fan comprising the vanes a, mounted on the armature-shaft a of the motor a. The motor a is of any suitable construction and is mounted loosely, so that it can turn from one side to the other on the upright stem 1) of the base B, which rests in the ball-bearin gs b and b The motor is prevented from becoming detached from the base by the screw 1), which projects into the circumferential groove 1) of the stem 1). The base 13 further carries a circumferential l groove b, in which are mounted the stops b which are conveniently in the form of setscrews adapted to be adjusted in the said groove 1) to regulate the distance of the oscillation.

The fan is, as is usual, inclosed in a wire guard O, which is attached to the motor by means of the arms 0. At the lower side of this wire guard and in substantially the same vertical plane as the center of the fan is a horizontal sleeve 0 into'which is inserted the arm d of the oscillating device D. From the arm d extend two arms d provided each with a hook, as (:1 insertedinto abushing d of a vane 61 on each side of the center of the fan and held there by means of a screw d. From the other end of the arm d extends the projection d to engage alternately with the stops b of the base B. To limit the tilting motion of the arm (1, a buffer (i acting against the wire guard, is carried by the said arm. If one of the vanes d now be in the path of the current of air produced by the fan, as shown in Fig. l, the other vane will be out of the path of the current of air of the said fan. The force of the air coming from the fan as it rotates will turn the said fan until the projection 01 engages with one of the stops b Which has the eifect of stopping the turning motion and of causing the other one of the two vanes 01 to move into operative position, while the first-mentioned vane d will move out of operative position, when the said fan is turned back again until it'is reversed by the engagement of the projection 01 with the other stop b when the operation is repeated. To vary the speed of the oscillation, the vanes 01 are I inclined more or less or not at all, as shown in Fig. 2, the set-screw d permitting such adjustment.

The vanes (1 will preferably be placed in moving each vane into and out of the path of the current of air produced by the fan, the

arrangement of the parts being such that when one vane is moved into operative posi-' tion, the other is moved out of operative po-s sition.

2. The combination with a fan, of means for causing it to oscillate as it rotates, com-. prising two vanes, one on each side of the center of the fan, means for alternately moving each vane into and out of the path of the current of air produced by the fan, the arrangement of the parts being such that when one vane is moved into operative position,

the other is moved'out of operative position,

and means for adjusting the said vanes theieby regulating the speed of the oscillation.

3. The combination with a fan, of means for causing it to oscillate as it rotates, comprising two vanes, one on each side of the center of the fan, adjustable stops for alternately moving each vane into and out of the path of the current of air produced by the fan, and for regulating the distance of the oscillation, the arrangement of-the parts being such that when one vane is moved into operative position, the other is moved out of operative position. 1

4. The combination with a fan, of means for causing it to oscillate as it rotates, comprising two vanes, one on each side of the center of the fan, and means for alternately moving each vane into and out of the path of the blast produced by the fan, the arrangement of the parts being such that when one vane is moved into operative position, the other is moved out of operative position.

5. The combination with a fan, of means for causing it to oscillate as it rotates, comprising two vanes, one on each side of the. center of the fan, means for alternately moving each vane into and out of the path of the blast producedby the fan, the arrangement O he p r 'sbe ng u t a iwhen one vane is moved into operative position, the other is moved out of operative position, and means for adjusting the said vanes thereby regulating the speed of the oscillation.

6. The combination with a fan, of means for causing it to oscillate as it rotates, comprising two vanes, one on each side of the center of the fan, adjustable stops for alternately moving each vane into and out-of the path of the blast produced by the fan, and

for regulating the distance of the oscillation,

the arrangement of the. parts being such that. when one vane is moved into operative position, the other is moved out of operative position. Y

7. The combination with a fan, of means, for causing it to oscillate as it rotates, comprising two vanes, one on each side of the center of the fan, a horizontal sleeve in substantially the same vertical plane as the center of the fan mounting said vanes loosely, stops on either side of the center of the fan, and a projection connected to the vanes for engaging with the said stops to alternately move each vane into and out of the path of the current of air produced by the fan, the arrangement of the parts being such that when one vane is movedinto operative position, the other is moved out of operative position.
